There are serious projects using distributed ledger technology that are trying to solve for "this distributed ledger entry stands for this real-world container of goods" or "this particular pallet," or "this particular box on that pallet, or "this particular diamond in that box" or "this particular fish."

But the application-level definition of parsing and comprehending what an entry in a ledger stands for is not universal. These are proprietary, or at least, communally-held paradigms being set up independently by each ledger designer.

We're lacking universal grammars so that the logic of an item designed to operate on distributed ledger X would be recognized or honored if migrated to distributed ledger Y.
